Electric actuator LA-2500

lineardouble-actingaluminum

Overview
LA-2500 linear actuators provide reliable linear positioning for dampers, combustion controls, gates, diverters, hydraulic variable-speed drives and other industrial linear applications. AC powered, self-contained, bi-directional and internally geared, units deliver up to 7,117 N (1,600 lbf) thrust; some models support continuous modulating duty up to 2,000 starts/hr.

Applications

• Damper and valve positioning
• Combustion and process control
• Gate, diverter and slide actuation
• Hydraulic variable-speed drive actuation

Key features

• Self-locking drive system holds last position and prevents backdriving up to the thrust rating
• Available in single-phase or three-phase AC power
• Standard manual override
• HART® communications option available
• Automatic thrust limiting
• Anti-condensation heater and thermostat
• Mechanical thrust overload protection to prevent motor burnout
• High modulating duty for improved process control
• High positioning accuracy for better flow and process regulation
• Minimal maintenance requirements reduce plant downtime
• Lightweight, anti-corrosive cast aluminium housing
• Grease-lubricated for mounting in any orientation
• Rain shield and bellows cover to prevent water intrusion

Range
Part of the LA-2000 range of heavy-duty linear actuators.
